主要特点与优势

Superior Solvency: Exhibits strong dissolving power for a wide range of resin systems, including nitrocellulose, acrylic, epoxy, and polyester.
Low Volatility: An extremely slow evaporation rate ensures prolonged “open time,” allowing for optimal leveling and a high-gloss finish.
Hydrophobic Profile: Reduced water solubility compared to standard glycol ethers makes it ideal for moisture-sensitive formulations.
Improved Safety: As a P-series solvent, it offers a significantly lower toxicity profile and lower vapor pressure than E-series counterparts.
Viscosity Control: Effectively reduces the viscosity of high-solids formulations, improving sprayability and application consistency.
Mild Odor: Facilitates use in confined industrial spaces and indoor architectural applications.

技术亮点

Molecular Formula: C₉H₁₈O₄
Boiling Point: Approximately 209^circC (408^circF) at 760 mmHg.
Flash Point: 86^circC (187^circF) (Setaflash Closed Cup), classifying it as a combustible liquid rather than highly flammable.
Evaporation Rate: 0.015 (n-Butyl Acetate = 1), categorizing it as a very slow-evaporating solvent.
Vapor Pressure: 0.08 mmHg at 20^circC, contributing to low VOC emissions in specific regulatory frameworks.
Specific Gravity: 0.976 at 20^circC.
Solubility: Limited solubility in water (approx. 7% at 20^circC); fully miscible with most organic solvents.
